Power for the mining-stack of Raspberry Pi’s

I have been running the Raspberry Pi mining-stack for a couple of days and I noticed that only on two of the Raspberry Pi’s the power LED was on. Although not all of the power LED’s were on I still could connect to each of the Raspberry Pi’s. After doing some reading up on the Raspberry Pi it turns out that those LED’s will only turn on if the Pi’s receives enough power.

Only some power LED's are onOnly some power LED's are on

This made me decide to get a different power supply to power the Raspberry Pi’s and ordered an Anker PowerPort 5 with 5 USB Ports 12A.

With this new power suplly the power LED on all the connected Raspberry Pi’s are on .

All power LED's onAll power LED's on

Also with the new power supply I seem to be getting a slightly higher hash rate, but that might just be coincidence.
